I have 8 cats,2 of them weigh close to 30lbs. I was worried about the stability,as the old one,would tip over. This is the best cat tree,sturdy,stable and well made. All of my cats love it and there has been 4,at a time on it,all competing for the top perch.They have taken the toy off,several times,but it is easy to re-tie.More than 5 stars.and Wayfair had it to me in 2 days.
